Low-reduction, high-torque actuators and an endoskeleton structure
Pancake-motor actuators with low gear reduction keep reflected inertia low and preserve backdrivability. Arms are built as an endoskeleton rather than an exoskeleton, cutting volume and cost, and the same actuator modules are reused from the MILLY arm to the BELLO and BELLO mini humanoids.
